ASUS sold this 14-inch VivoBook under two names, so a K403 and an X403 can sit side by side in listings and share most of their hardware. The K403 is the VivoBook 14, a slim consumer model from about 2019 onwards with 8th-generation Intel Core processors and a 14.0-inch 1920x1080 panel, though later VivoBook 14 generations moved to different screens and housings. A full range of parts is stocked for the K403 family: replacement screens, batteries, keyboards, palmrests, hinges, display cables, DC jacks and cooling fans among them. Match the full model code on the underside of the laptop against the model table on this page before ordering, since the variant code decides which parts fit. Parts can be picked up from the Maidstone workshop in Melbourne, or the laptop can be left there for repair.
